3- If an equilateral triangle has 3 equal sides, it also has 3 orders of rotational symmetry.
An order of symmetry is the number of times a line of symmetry can be drawn through a shape. For example, a square has four orders of symmetry: One up and down, one left and right, and two diagonal. A rectangle has an two orders of symmetry. A circle has an infinite number of orders of symmetry.
If it's a regular 8 sided octagon then it rotational symmetry to the order of 8
No, but it HAS reflection symmetry
A parallelogram.
3- If an equilateral triangle has 3 equal sides, it also has 3 orders of rotational symmetry.
A scalene triangle has one order of rotational symmetry.
An order of symmetry is the number of times a line of symmetry can be drawn through a shape. For example, a square has four orders of symmetry: One up and down, one left and right, and two diagonal. A rectangle has an two orders of symmetry. A circle has an infinite number of orders of symmetry.

It need not have any rotational symmetry or it can have 5.
No, but it HAS reflection symmetry
A parallelogram.
The rectangle's rotational symmetry is of order 2. A square's rotational symmetry is of order 4; the triangle has a symmetry of order 3. Rotational symmetry is the number of times a figure can be rotated and still look the same as the original figure.
It have 4 axis of symmetry . Two Perpendiculars and two Diagonals
Because the circle's diameter has infinite lines of symmetry
